gpbiometrics: Process and Report Gazepoint Biometrics Data

Gazepoint-native tools for reproducible analysis and reporting of Gazepoint Biometrics and GP3-derived physiological, gaze, pupil, fixation, AOI, marker, and event-level exports. The package supports import, validation, preprocessing, missing-value imputation, EDA/GSR, SCR epoching, IBI/RR/HRV, PPG/pulse workflows, pupil blink detection and cleaning, gaze filtering, fixation summaries, engagement-dial indices, multimodal trial regressors, quality reports, exclusion and QC recommendations, synthetic eye-data generation, and interoperability or workflow-inspired helpers for common psychophysiology toolchains. The package is designed for transparent, CRAN-safe, scriptable analysis rather than as a full clone of external commercial or open-source toolboxes.
